SPECIFICATION forming part of Letters Patent No. 3 .7 t d March 22, 1837- Apnlication filed January 11, 1887. Serial $0. 223,994. (No model.)

To all whom it may concern:

Be itkn own that l, HENRY DnEYrUs, of the city, county, and State of New York, have invented certain newand useful Improvements in Initial Stones, of which the following is a specification.

This invention relates to that class of stones for jewelry purposes on which an initial is held.

The object of my invention is to facilitate the attaching of the stone and the initial to the article of jewelry, also to hold the initial securely on the stone.

The further object is to provide a striking and novel effect by means of the initial.

The invention consists of an initial made of a stone known as tiger-eye or tigerstone, which initial is held on an onyx or like stone in the ring.

The invention further consists in the combination, with an article of jewelry, of an onyx or like stone and the initial of the tigereye or tiger-stone, and screws passed through an aperture in the article of jewelry, through apertures in the onyx, and screwed into threaded apertures in the back of the initial, whereby said initial is held on the onyx or like stone and the stone is held in place on the article ofjewelry.

In the accompanying drawings, Figure 1 is a face view of a ring provided with my improvement. Fig. 2 is an enlarged sectional view on line .r :r, Fig. 1, parts being broken out. Fig. 3 is an enlarged view on line y y, Fig. 1.

Similar letters of reference indicate corre sponding parts. V

The ring A "s made in the usual manner and provided with a square, flat, or other frame or setting, 13, for receiving the flat or curved onyx or like stone 0. The initial D is made of a stone known as the tiger-eye or tiger-stone, which has a striking brilliant yellowish phosphorescent appearance,and produces a very striking effect upon the onyx or like stone, or on any other stone. The onyx is provided with one or more apertures, E, and the back-plate F of the ring -that is,the plate on which the back of the onyx or like stone rests-is provided with corresponding apertures, G, in line with the apertures E. At

said apertures theback-plate F is slightly countersunk, as shown at H, for receiving the head I of a screw, J, which screw is passed through the aperture G in the plate F and' screwed into the back of the stone initial D and drawn up tight. Thereby the initial is held firmly on the onyx, and at the same time the onyx is held securely in the frame of the ring. N0 cementing whatever is required.

In case the initial breaks in the mounting or layer the screws J are withdrawn and a new initial placed on the onyx. There is no necessity of removing the onyx from its frame or setting. As the head of the screw rests against the metal of the ring or other article of jewelry, there is no danger of breaking the thread in the apertures in the initial, as the metal against which the screw-head rests can give slightly when the screw is drawn up tight.

Buttons, lace-pins, lockets, watch-cases, and other articles of jewelry may be constructed in a like manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with an onyx or like stone, of an initial made of stone and held on the face of the onyx, substantially as shown and described.

2. The combination, with an article ofjewelry, of an onyx or like stone placed in the frame of said article and having apertures extending transversely through said stone, :1. stone initial on the face of the onyx or like stone, which stone initial is provided in its rear side with screw-threaded apertures extending only partly transversely through the stone, aud screws passed through apertures in the article of jewelry and through the apertures in the stone, and having their upper ends screwed into the screw-threaded apertures in the under side of the stone initial, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

HENRY DREYFUS.
